Abstract
The utility model relates to an asymmetric pyramid shaped bridge tower belongs to the bridge tower structure of the novel cable -stay bridge of water conservancy project. King -post bottom respectively with respective tower mound fixed connection, the top of the tower intersect at the top, tower mound and bridge tower basis fixed connection, horizontally roof beam interconnect is passed through to bridge tower counter weight position in the top of the bridge tower basis between the tower mound between each king -post, wherein king -post no. 1 is connected through roof beam no. 1 between two with the king -post, king -post no. 2 is connected through roof beam no. 2 between three with the king -post, king -post no. 3 is connected through roof beam no. 3 between four with the king -post, king -post no. 4 is connected through roof beam no. 4 between one with the king -post, roof beam no. 2, roof beam quartering do not be two perpendicular with the bridge axis of the bridge axis of bridge floor no. 1, bridge floor no. 2, bridge floor no. 1, bridge floor policy of "literature and art should serve both people and socialism" broken line bridge floor. The advantage is novel structure, sets up side direction that counter weight district both can keep balance the transmission of the broken line bridge floor load that topples, can also keep balance the unsymmetrical loading that asymmetric bridge floor transmitted, can be used to water conservancy project structural design under the non - symmetrical arrangement circumstances.
Description
Technical field
The utility model belongs to the bridge tower structure of water conservancy project New Cable-stayed Bridge.
Background technology
As everyone knows, cable stayed bridge is longspan structure, can adopt different arrangements for different geology, orographic condition.General single tower slant-pull structure mostly is symmetrical line and arranges, can be balanced the load force of bridge floor transmission by tower.Middle pyramidal structure is interacted by symmetrical load to cut down load action, can reduce structure-bearing system size, reduce Structural Engineering amount, effectively reduce investment outlay.According to the actual conditions of engineering site, the both sides bridge floor of cable stayed bridge need adopt the broken line arrangement form of certain angle, broken line angle within the scope of 0 ~ 30 degree, the bridge tower of so usual symmetry because of the bridge floor of both sides asymmetric, can non-symmetrical load be produced, easily cause side direction and topple.
Summary of the invention
The utility model provides a kind of asymmetrical pyramid bridge tower, with solve symmetrical bridge tower because of the bridge floor of both sides asymmetric, can non-symmetrical load be produced, easily cause the problem that side direction is toppled.
The technical scheme that the utility model is taked is:
Be fixedly connected with respective tower pier respectively bottom four king-posts, the roof intersection tower top of four king-posts, tower pier is fixedly connected with pylon foundation, bridge tower weighted areas is positioned at above the pylon foundation between tower pier, beam by level between each king-post is interconnected, wherein be connected by beam one between king-post one with king-post two, be connected by beam two between king-post two with king-post three, be connected by beam three between king-post three with king-post four, be connected by beam four between king-post four with king-post one, described beam two, Liang Si respectively with the bridge axis one of bridge floor one, the bridge axis two of bridge floor two is vertical, bridge floor one, bridge floor two is broken line bridge floor, broken line angle is α, 0 degree of ﹤ α ﹤ 30 degree.
The utility model has the advantages that novel structure, side direction that weighted areas both can balance the transmission of broken line bridge floor is set and topples load, the unsymmetrical load that asymmetric bridge floor transmits can also be balanced, can be used for Design of Hydraulic Structures in asymmetric arrangement situation.
